WHEEL.

Application filed May 22, 1925. Serial No. 32,175.

This invention relates to wheels and particularly to an improved construction of stamped wheel formed from sheet metal and has for an object to provide a construct on which may be readily utilized as clotheshne pulley wheels, hand wheels or wheels capable of use for other purposes.

Another object is to provide a sheet metal wheel with a rim stamped from a single piece 19 of sheet metal and formed continous.

A still further object of the invention is to provide a pulley wheel in which a hub structure is provided capable of easy assemblage without distorting any parts of the Wheel structure.

In the accon'ipanying drawings Figure 1 is a sectional view through a clothesline pulley wheel disclosing an embodiment of the invention.

Figure 2 is a sectional View through Figure 1 on line 2-2.

Figure 10 is a fragn'ientary sectional view showing a modified form of the invention wherein the rim is turned inwardly instead of outwardly.

In constructing a wheel, it has been found very desirable to make the rim of the wheel of a single endless piece. Heretofore, the ring has been made from fiat material stamped into the desired shape and then bent so that the ends would meet or overlap.

Various means have been provided for securing these ends together so as to con'iplete the rim. In some instances, the spokes of the wheel were provided with spaced rivet extensions acting as means for holding together abutting ends of a rim. In connect ing the ends of the various members together as described, extra work was required and also the finished product was not as accurate as might be desired. In order to overcome these difficulties and to make a simple but very accurate and desirable structure, the present invention includes the formation of the ring or rim of the wheel in one continuous piece.

Referring to the accompanying drawings by numerals, 1 indicates a ring formed of sheet metal and stamped into the desired shape which is sen'ii-circular in cross section as illustrated in Figure 2. This ring or rim is formed in a die and pressed or stamped into the complete finished shape as shown in Figures 1, 2, 3 and 6. It will be noted from Figure 1 that there is no joint at any point as the ring is made continuous throughout, thereby giving a very smooth surface for the rope used thereon. The ring is made from fiat sheet metal and is stamped or rather formed into the finished shape as illustrated in Figures '1 and 3 by suitable dies. The ring 1 is provided with a plurality of spokes 2 which are made from stamped sheet metal, said spokes being formed double, namely, with sections 3 and 4-, said sections being identical in construction and formed as illustrated particularly in Figures 4 and 5.

As indicated in Figure 4, section 3 is pro vided with an aperture 5, pressed up portions 6 and 7 acting as stiffening members or beads and specially constructed end portions 8 and 9. The end portion 8 is shown at the left in Figure 5 and consists of a pair of eX- tensions 10 and 11 adapted to be forced' through suitable apertures 12 in ring 1. Between the base of these extensions, the section 3 is pressed to one side as indicated by the pressed port-ion 13. By pressing this section to one side, a depression 14 is presented adapted to receive the pressed out portion 15 of the opposite section, namely, section l. An extension 16 projects from the pressed out portion 15, said extension being adapted to project through the central in Figure 5.

opening 17 when the spoke is in position. It will be noted that the section 3 at end 8 is formed as shown at the left in Figure 5 and end 9 is formed as shown at the right It will be understood that the pressed portions 13 and 15 are notsharply defined but are only pressed slightly as more accurately indicated in Figure 9 from which it will be observed that the portion 15 is only pressed to one side with the extent of about half the thickness of the material. The same is true in regard to the pressed. portion 13 and when the portion 15 .lits into .the depression or socket l t, the projections 10, 11

and 16 willallbe in line whereby then-cspective apertures 12and 17 may be positioned centrally oi the ring l as shown in Figure This permits readypunching of the ring for forming these apertures and .alsopermits easy riveting ot the extensions 10, 11 and 16. In addition to arranging the projections 10, 11 and 16 centrally for easy riveting and the like, the upper edge of portion 13 will fit snuglyagainstthe rim 1 and also theshouldersor edges 18 and 19 will also fit snugly againstthering l and thereby not as an additional support orb. 'ace for making a strong, firm structure.

The wirious spokes 2 are connected together at the point of crossing by a member 21. which is associated with the tubular member 22, member 21 acting as a hub casing while membcri-Q acts as a bushing and also as aspacinn' memberiwhen the rivet or shaft 23 is placed in position as showninFigure 2. lhe tubular members 21 and 22 may be made from any desired material but preterably the bushing 22 ismade from bronze whereby an easy turning structure is presented. The tubular member or casing 21 is provided with two series ofpressed up lugs Ql and 25 as indicated in Figures 2 and 8. \Vhen assembling the hub and spokes, the spokes are titted over the ends oi'ythe cas ing 21, whichends pass through the various openings 5 so that one set of sections 3 and et will press against the projections and 2a and the. other set of sections 3 and l: will rest on top of theiirstset of sections. This completes the wheel structure and said wheel structure is ready for use as apulley or for any other purposes desired. \Vhen used. as a pulley it is mounted in the guard and the hanger 27 as shown in Figures 2, 6 and '7. The guard 26 is made sutlicientlywide to permit the hub 20 to be readily fitted into position but before it is titted into position a hushingflil is supplied, which bushing is preferably slightly longer than the tubular member :21 after the tubularmember has been bent over as. shown in Figure 2. This will cause the guard 26 torpress against the bushing 22 andallow the hub to rotate loose. The pintle or rod 23 18 then inserted and upset or riveted asshown in Figure 2. By

.for the hanger 27.

has been properly riveted the wheel may freely rotate.

It will be noted that by this constrl'iction and arrangement the guard 20 is not bowed or distorted "when aj'iplying the wheel but the wheel is merely loosely placed in position and rod riveted lirmly in place.

After all the parts 0). the wheel have been assemliiled, therod 23 is riveted into position anda very rigid connection is provided It will also he noted that a minimum number oi parts a to used while iiuaximum strength is secured. Under some circumstai'ices, instead of haviilig a groove "formed in the ring 1,.tl1e parts may be reversed as shown in l igure 10 wherein the ring 1 is formed filCfillllllQtl in cross section with the o ircning facing the spokes. This form ot wheel particularly in pairs on diametrically opposite sides of.

the rim with the openings of each group in a straight line, spokes for said rim, each of said spokes beinn lformed with a pair of sections, each section being :lormed atone end with a pair of spaced tcnons and at the opposite end with a. single tcnon, said sections being arrangedso that. the end of one section having two tcnons thereon is locked against the end of the other-section having one tcnon, all of said tcuons being offset in such amanner that when the tenons are litteil into said ()IJUlllllgHlll[ \,\\'lll be zlllllfllutl and interlocked.

In a metallic wheel, a rim and a plurality of spokes therefor, and a hub volumetinc said spokes. eachot' said spokes belug Formed with a pair oi sectionmcach section having a central aperture, :1. pair of tenons extending from one end adjzu'ent the edges and a single tenon extending from the opill) l if) from the plane of the section and the space between the tenons at the opposite end being also oltset whereby When another section is superimposed thereon with the single centrally positioned tenon located between the two tenons they will all be aligned and interlocked.
